Motherboards Point, Thread "Has someone tried to add interrupt support to Riscy Pygness?" - “I just started to play with Riscy Pygness on target part of LPCXpresso 1769 board... The only thing which seems to be lacking is interrupt support. Well, I can write the interrupt service routine in assembly and add it to the kernel, and it will be the most efficient solution. However for interactive experiments it would be much nicer to have possibility to implement ISR as a Forth word. Such functionality is available in the latest version of amforth for ATmega's”.
